Paid MCP Servers:
Monetize Your MCP Server
Charge Claude, GPT and other agents per tool call — in USDC, with no signup or API keys. Below: a curated list of paid MCP servers and the open-source infrastructure to monetize your own, from the 328+ MCP projects we track.
Can you monetize an MCP server?
Yes. Gate your MCP tools behind x402 (HTTP 402 Payment Required) so an LLM client like Claude or GPT pays a small USDC amount per call before the tool runs. The agent needs no account or API key — it pays with a wallet, and you get paid per request, in real time.
How paid MCP servers work
- An agent (Claude, GPT, …) calls a tool on your MCP server.
- The server responds with HTTP 402 + payment terms (amount, USDC, chain).
- The agent signs and pays from its wallet; a facilitator verifies & settles.
- Your tool runs and returns the result. You earned a micropayment — per call, instantly.
JWT Secrets — a real x402-paid API
A working paid MCP server you can point an agent at today. It exposes JWT tools — decode, verify and crack — and charges per call over HTTP 402, settling via x402 (USDC on Base) or MPP (Tempo).

Frequently asked questions
Can you monetize an MCP server?
Yes. By gating your MCP tools behind x402 (HTTP 402 Payment Required), an LLM client like Claude or GPT pays a small USDC amount per call before the tool runs. The agent never needs an account or API key — it pays with a wallet, and you get paid per request.
How do I add payments to an MCP server?
Wrap your MCP tool endpoints with x402 middleware. When the tool is called, the server returns a 402 with payment terms; the agent signs and pays in USDC; a facilitator settles it; then the tool runs. Several open-source projects (above) provide drop-in infrastructure so you don’t build settlement yourself.
What are the best paid MCP servers?
It depends on what you sell. Data/research MCP servers (like live market or web data) and tool/API gateways are the most common paid models today. The list above is a curated starting point; browse the full directory for more.
Which payment protocol do paid MCP servers use?
Almost all use x402 with USDC settlement on Base (and increasingly Solana). x402 is HTTP-native, which maps cleanly onto MCP’s request/response model and lets agents pay autonomously.
Do clients like Claude support paying MCP servers?
The payment happens at the protocol layer: the agent/client holds a wallet and responds to the 402 challenge. Tooling like the projects above bridges MCP tool calls to x402 so the client can pay automatically without human approval for each call.
